摘　　要：在火力发电机组中,由于煤质的变化,燃煤的粉煤灰易造成锅炉脱硝、空预器、电除尘等烟气系统的堵塞,从而导致引风机抢风。本文从火力发电厂引风机抢风的实际原因进行分析,结合风机自身的性能曲线,提出解决实际问题的方法,避免机组运行中引风机抢风的发生。In thermal generating units,due to the change of coal quality,the fly ash of coal combustion is easy to bring the blockage of the flue gas system such as boiler denitrification,empty preheater,electric dust removal,etc.,which cause the fan blowing.Combined with the performance curve of the fan,the method of solving practical problems is put forward to avoid the occurrence of the fan rush during the unit operation.

关 键 词：抢风 性能曲线 管道阻力曲线 流量
